,CAR-BRAKE-QPERATING MECHANISM.

; for retaining the brake handle or wheel in a fixed position after it has' been moved, without the use of a ratchet wheel, pawl, dog, or similar device.

Another important object of my invention is, to provide a mechanisrnoftheabove type that will insure perfect safe'tyof a brakeman,

when operating the same, thus obviating many accidents due tothe slipping and sudden'releasmg of brake mechanism.

The inven tion comprehends a cable or chain drum, a gear wheel meshing with a worm, brackets for supporting the same, and a main operating shaft, all these elements being arranged at the top and end of a freight car, whereby they can be easily actuated by a brakenian The invention will be presently described in detail' and reference will now be had to a drawing forming part of this specification.

In the drawing Figure l is an end view of' a portion of a car, partly broken away to illustrate the brake mechanism, Fig. 2 is an enlarged front elevation of the mechanism, Fig. 3 is aside elevation of the same, and Fig. 4 is a vertical sectional view of the worm.

Reference first being bad to Fig.1 of the drawings and then to the remaining figures, the reference numeral l designates a portion of a car having roof beams 2, and a roof 3. Suspended from the roof beams 2 or a plate 4 carried thereby is a metallic hanger or bracket 5, and journaled in this bracket is a vertically disposed shaft 6 having its upper end extending through one of the beams 2 and the roof .3, and provided with a brake wheel or handle 7. Upon the shaft 6, within the bracket 5, is fixed a reinforced worm 8, the reinforcement comprisin a tapering integral sleeve? adapted to relieve the worm 8 2 of any strain due to moving the shaft 6. The

roof beams Z or the plate 4, pontiguous to the Specification 'of Letters Patent.

bracket 5, are provided" with depending brackets 10, and journaled in said brackets is a horizontal shaft 11, one end of said shaft being rovided with a gear wheel 12, meshing with t e worm 8. Upon the shaft 11, between the brackets 10, is mounted a cable or chain drum 13, to which is suitably secured a chain or cable 14: This chain or cable 1&1 is adapted to extend down through the car andconnect with the brakerigging (not shown) beneath thecar.

It is apparent from the construction just described that it is onlynecessary to turn the brake handle or wheel 7 to wind or release the chain or cable 14, it being impossible for a movement of the drum 13 to affect the worm a, the shaft 6 or the handle or wheel 7 Since the mechanism is housed within the car 1, it is'not susceptible to deterioration from the forces of. nature, or to breakage by ordinary use. The mechanism has been designed solely for cars and as such will be hereinafter claimed.

. Having now describedmy invention, what I claim as new is the combination with a car and the roof thereof, of brackets suspended from said roof, a shaft journale'd in one of said brackets and extending above said roof, a brake Wheel carried thereby,,-a reinforced worm mounted. upon said shaft, said reinforcement comprising a ta ering sleeve, a shaft journaled in the other of said brackets, a gear wheel carried by said shaft and meshing with said worm, a drum carried by said shaft, and a chain or cable connecting with said drum,

substantially as, and for the purpose de-' scribed.

2. In a car brake operating mechanism, the combination with acar and the roof thereof, of brackets suspended from said roof, a vertically disposed shaft journaled in one of said brackets, a reinforced'worm carried thereby, a horizontal shaft journalod in the other of said brackets, a gear, wheel carried by said shaft and meshing with said worm, a drum fixed. on said shaft,- and a chain or cable connecting with said drum, substantially as described.

In testimony whereof I affix mysignature in the presence of two witnesses.
